Temperature and Salinity Workup
Initial conclusions/questions:
1) Gotta throw out most, if not all EELD1 salinity data. I think these instruments ended up in the mud. Keep the StarOddi temp data from this station.
2) RBR seems more accurate than Star Oddi* (e.g fewer big dips in salinity/conductivity), but still has a scatter of questionable conductivity data. There’s no “cup” to be fouled by sediment, so what is happening?
3) Some of the “non-anomoulus” data I would still throw out. After talking to Tim, this data should be left in but “flagged” in a new column.
Compare instrument types (color points) to YSI data (black points)
EWLD1 and KALD1 could use calibration
